To all whomtt may cohdeht:

Bloomington, in the county of McLean and State of Illinois, haveinvented certain new and usefulglmprovements in AutomaticReceiving-Tables for Printing-Presses, &c.; and- I do hereby declarethat the following'is ,a full, clear, and exact description of the same,reference beingmade to the accompanyingdrawings, forming a part of thisspecification, and in whicha,

Figure 1 isa t'op'view'; Fig. 2, an end view; Fig. 3 ,an enlarged bottomview. Fig. 4is a detail view.

, This invention relatesto improvements in automatic tables forreceiving and straightening sheets of paper .as they come from printingpresses, paper-mills, lbook-binding machines, ruling-machines, &c.; andthe invention consists in. the several combinations of, parts,"as willbe hereinafter fully described.

In the drawings,; A representsthe paperreceiving table, slottedvat' a,a. a a, through which-{pass the vertical paper-guides a, forstraightening the paper as it is thrownon the table from the fly of theprinting-press. These guides at are adjustably secured to the automaticslides B by nuts or set-screws b, as desired, whereby said guides can beadjusted to receive different-sized sheets of paper. D are metallicguides attached to the under side of the-tableA, and withinfwhich theslides B work. 0 representsa back guide for the paper to rest ,againstonthe tableA, and said guide 0. is adjustably securedat any desiredposition in the metallic guides E (set in, the table so as to be flushwith the top thereof) by means of the thumb-screws c,- washers c, andslides e, as clearly shown in Figs. 1 and 4, ,F represents a removableside guide, to be used only when the paper is cut by the press, forlaying two sheets of paper at once.

The inner ends of the four slides B are connected to the ends of thepivoted cross-rods g g by connecting-rods d d 01 d and theconnecting-rods (1 d with one end of each of the cross-rods g g, arepivoted to the rods h h, which are secured to the reciprocating bar H,working in the guides it i. The reciprocating rod H communicates areciprocating movei ment to the guide-slides B through the me- Be1tknown that I, MORRIS D. WILKINS, of

'dium of the connecting and pivoted cross-rods. J is a bar arranged atright angles to the bar H, and which is pivoted to the right-angled barj secured to the standard j, and said bar J is supported in the slottedstandard or guide j as clearly shown in Figs. 2 and 3, and is alsoconnected with the bar H by the pivoted bar I, as shown in Fig. 2. Thispivoted bar J,vwhioh communicates motion to the bar H in one direction,or moves said bar backward, is operated through the medium of the arm K,resting in guide 70, and pivoted to one end of the lever L, centrallypivoted in the standards I, and having its other end connected with theadjustable guide m, secured in the slot m of the pivoted bar J, by meansof the crank- -rod m. A spring, H, upon the bar H, produces the recoilor return movement of said bar to its original position.

The table A is supported by the cross-legs N, having guides n 0 on theirfeet, which are adjustably secured to the transverse bars or slides O,secured to the under side of said table by set-screws n, and to thelongitudinal rods P, secured to the supporting-base R by set-screws 10,whereby the table is adapted to be adjusted lengthwise and sidewise toaccommodate it to the different positions of the machine from which itreceives its paper. The legs N, where they cross each other, are securedtogether by the vertical bar S and set-screw s, by which means the tableis also adapted to have a vertical adjustment.

T is a bar, supported by springs t, for easing of the fly when throwingpaper on the table from the press, and also for the fly to rest on afterthe paper is delivered upon the table.

The table is first placed in position to receive the paper thrown fromthe press or other machine it is to be connected with. The back guide isthen adjusted up to within one inch of the paper to be laid on thetable. The arm K is then pushed in as far as it will go, and the guidesadjusted and secured in the slides up to the edge of the paper, afterwhich said arm K is released, so as to throw the guides back in properposition to receive the paper between them and the back guide.

The arm K; through the medium of which the guides are operated, will beoperated by the shoe connected with the bed of the print ing-press, andas the bed moves toward the receiving-table the shoe stakes the said armK and pushes it forward. This movement of the arm operates the guidesthrough the medium of the intermediate mechanism before described, whichstraighten and force the sheets of paper thrown upon the table by thefly of the press up against the back guide G, and when the shoe isreleased from contact with said arm K the spring on bar or rod H returnsthe guides and other mechanism to their original position.

To avoid the fly of the press striking against the guides. the table canbe adjusted sidewise in either direction to prevent it, and the tablecan be moved forward and backward on the rods P to lengthen or shortenthe stroke of the arm K.

The table can also be adjusted vertically, to accommodate itself to theheight of diflerent presses.

On job-presses the table is disconnected from the legs, and used thesame as ordinary feed-boards by connecting the arm K to the platen as itcomes back to be fed.

On ruling-machines the spring-bar T is to be dispensed with, and thetable to be used in the same manner as the common tables used for thatpurpose, with the exception of connecting the arm K with the machine foroperating the guides.

I do not desire to limit myself to the shoeand-arm connection foroperating the mechanism that moves the guides, as the connection may bemade with the fly by means of a rod and binge, so that when the rod 'towhich the fly is attached turns the same it will move the rod backwardand forward, thereby operating the guides mechanism. A board can also beused to connect the automatic guides on each side, so that all parts ofthe sides of the sheets may be pressed into place, instead of only atthe point of contact with the uides, which may be found necessary whenaying and straightening thin paper.

My improved table can be used, in connection with any cylinder-press,for laying and straightening paper as it comes therefrom, and either oneor two sheets at a time, by re- I moving or attaching the side guide F.It can i be easily adjusted, and keeps the paper clean and straight forthe cutter, (if to be cut or trimmed,) or puts the paper in condition tobe bundled or packed, as every sheet is laid so as to come out inthe'ream as it was bei'oi'e going to the press. On boo'lbwork oi two ormore impression jobs it saves the labor of straightening the paper byhand before going to the cutter, and lessens the work of the binder intrimming it 011', The adjustable slides admit of the table being used onall sizes of paper from crown to the largest size that can be used onaeyiinder-press; and it will lay paper from the thinnest tissue to theheaviest card-board. It is easily adapted to be used in connection withother forms of printing-presses; and also in paper-mills for laying andstraightening all sizes of paper in first-class order, therebydispensing with extra help employed for that purpose. It is also usefullor laying papers in their proper order for book-binding; and also inreceiving paper from ruling-machines, and also for all other analogousmachines.

I claim as my invention--- 1. The combination, with the paper-receivingtable A, of the automatically-reciprocating and adjustable guides a' andadjustable guide (J, substantially as and for the purpose specified.

2. The combination with the slotted table A, having guide '0, of theguides a, s ides B, arm K. and intermediate mechanism, substantially asand for the purpose specified.

3. The combination, with t e guides a and back guide 0, of the removal)e guide 1?, substantially as and for the purpose specified.

4.. The combination of the table with legs N, having uides o, and silporting-base having the ro s P, suhstantia ly as and for the purposespecified.

5. The combination, wi'tlithe table having the slides U, and thesugporting-base having the rods P, of t 6 legs having the guides n 0,substantial y as and for the purposes specified.

6. The combination, with thereceiving-table, of the spring-bar T,substantially as and for the purpose specified. w

7. The combination, with the slides B, having the guides a, connectiiIngan'd cross-rods of the bar H, and spring substantially as and 'for thepurpose specili'ed.

In testimony whereof and that 1 claim the foregoing I have hereto set myhand this 9th day of August, 1877.
